Betreff: [Elecraft] K2 MDS numbers off
Hi all,
I attempted
Peter,
Thanks for the suggestion: T7 checked out ok with proper orientation and
proper number of turns. Another post mentioned checking RFC11, so I'm
checking that next.
Does anyone have a suggestion about a simple test oscillator/rf signal
generator kit to purchase to perform the signal
Many people have suggested using the XG2 as a signal source for signal
tracing.
My understanding from reading a previous post was that the 50 uV output of
the XG2 was too low to perform signal tracing on the receiver circuitry
(however, it's adequate for the transmitter circuitry).
I'd love to
Brian,
The XG2 will not work for that purpose at all, the signal level is too
small, and the noise pickup on a 'scope probe will likely be larger than
the signal.
The generator shown in the K2 manual is dirt simple, and does not have
to be carefully assembled. I built one Manhatten style
Hi all,
I attempted to calculate my K2's (S/N 6800) receiver sensitivity using an
XG2, but I'm getting numbers way off from what are listed in the XG2
instruction sheet.
Using a Fluke 117 multimeter, I'm measuring S+N = 0.132 Vrms and N = 0.034
Vrms, which I calculate MDS = -119 dBm. I'm
Brian,
Your K2 seems to be somewhat deaf based on your MDS measurements.
I would recommend that you do the steps in the K2 manual under Receiver
Signal Tracing to identify the failing stage. Once the failure point is
identified, we can offer additional assistance.
